What is void

Quick Scoop

Void usually means empty, nothing, or a lack of something. In programming, it often means a function returns no value; in everyday language, it can mean an empty space or a sense of absence.

Common meanings

• Everyday use: an empty space, gap, or nothingness.
[9][5]
• Programming: a return type that means the function does not send back a value.
[1][4]
• Legal use: something that is void has no legal force or effect.

In simple terms

If you hear “the void,” think emptiness. If you see “void” in code, think this function does an action but gives nothing back.

[1][5]

Example

In programming, a function that prints a message might be marked void because it does not return a result.

[4][1]

Bottom line: void means “nothing returned” in code, and “empty or null” in general language.
